Subject: [PATCH] ALSA: wavefront: Support PCM sync_stop
Git-commit: 48094a75cd7090aecc1b9b0dd0c5f1f70c7443cb
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518

The driver invokes snd_pcm_period_elapsed() simply from the interrupt
handler.  Set card->sync_irq for enabling the missing sync_stop PCM
operation.
